This paper links the theoretical and empirical literatures on interjurisdic
tional tax and regulatory competition, focusing on the case of state hazard
ous waste disposal taxes. It begins by demonstrating that local environment
al taxes can be inefficient, and that the inefficiency depends on the tax e
lasticity of polluters' responses. The paper then uses panel data from the
Toxics Release Inventory to estimate the magnitude of the tax elasticities,
and to demonstrate the empirical relevance of the theoretical inefficiency
of local taxes. (C) 1999 Elsevier Science S.A. All rights reserved.
